Dual role of silver in a fluorogenic N-squaraine probe based on Ag(i)–π interactions
2021
In the presence of Ag(I), the monoanion of cyano-N-squaraine (I) generates an intense fluorescence turn-on response. Experimental evidence and DFT calculations reveal a sequence of deprotonation-coordination events in which the Ag(I) ions play a dual role as a Lewis acid and coordinating metal. The observed effect is highly selective for Ag(I) compared to other metals.
The interplay betweenPinus sylvestris, its root hemiparasite,Melampyrum pratense, and ectomycorrhizal fungi: Influences on plant growth and reproduct…

Despite the extensive literature on mutual interactions between plants and mycorrhizal fungi, and host plants and parasitic plants, little is known about the outcomes of interactions when the three...
The Recent Development of a Sweet-Tasting Brazzein and its Potential Industrial Applications
2016
International audience; Brazzein is a small heat- and pH-stable sweet-tasting protein isolated from the West African plant, Pentadiplandra brazzeana. Brazzein combines a highly sweet potency, a long history of human consumption, and a remarkable stability, giving it great potential as a natural sweetener. Due to the difficulties of obtaining brazzein from its natural source, several efforts have been made to express brazzein using various heterologous expression systems. This chapter describes the biochemical, structural, sensory, and physiological properties of brazzein. We will summarize the current knowledge of the structure-activity relationship of brazzein. The biotechnological product…
Yersiniaspp. in Wild Rodents and Shrews in Finland
2017
Yersinia enterocolitica and Yersinia pseudotuberculosis are important zoonotic bacteria causing human enteric yersiniosis commonly reported in Europe. All Y. pseudotuberculosis strains are considered pathogenic, while Y. enterocolitica include both pathogenic and nonpathogenic strains which can be divided into six biotypes (1A, 1B, and 2-5) and about 30 serotypes. The most common types causing yersiniosis in Europe are Y. enterocolitica bioserotypes 4/O:3 and 2/O:9. Strains belonging to biotype 1A are considered as nonpathogenic because they are missing important virulence genes like the attachment-invasion-locus (ail) gene in the chromosome and the virulence plasmid. The role of wild small…
Cognitive representations of predicates and the use of past tenses in French: a developmental approach
1997
Two experiments examine how French 10-year-old children and adults relate past tenses to the semantic properties of predicate types in writing. Experiment 1 involved two tasks: graphically coding two predicate dimensions (durativity and resultativity), a task designed to assess cognitive representations of these predicates; and selecting past tenses in sentences which included previously evaluated verbs. Results show that (a) 10-year-olds and adults have comparable representations of durativity, but different ones for resultativity, (b) the adults associate process charac teristics and past tenses, but 10-year-olds do not. In Experiment 2, subjects only had to code graphically two dimensio…
Combined treatment of hidradenitis suppurativa with intense pulsed light (IPL) and radiofrequency (RF)
2019
BACKGROUND Hidradenitis suppurativa is a chronic inflammatory disease with high burden. Treatment options are often unsatisfactory. We assessed the effect of a combination therapy of intense pulsed light (IPL) and radiofrequency (RF). METHODS The explorative study included 47 patients and was performed as a prospective, monocentric, randomized, three-arm parallel-group design trial with a prior 12 weeks observation period. Treatment arms were IPL and RF monotherapies or IPL + RF combination therapy. After 12 weeks, all patients received IPL + RF for additional 12 weeks (cross-over). Primary endpoint was the change in active lesion numbers, secondary endpoint the change in Dermatology Qualit…
Data from: Effects of undergrowth removal and edge proximity on ground beetles and vascular plants in urban boreal forests
2019
Urban forests are regularly managed for human safety and aesthetic reasons, but they are crucial habitat for many species. Removals of undergrowth occur commonly in these forests, yet the ecological consequences of these operations are poorly understood. We sampled ground beetles (Coleoptera, Carabidae) and vascular plants along 20-m edge gradients in Finnish urban forests, in five stands treated 0.5−2.5 years earlier with undergrowth removal and in five untreated stands. We hypothesized that undergrowth removal and edge proximity would benefit opportunistic and open-habitat species, whereas shady-habitat species would be affected negatively. (1) Regarding carabids, diversity and evenness i…
Testo e aspetto: passato prossimo e passato remoto nei Confessionali siciliani antichi
2019
The Old Sicilian Confessionali are devotional texts of the fourteenth and fifteenth centuries with a very simple textual structure. In particular, two of them, to a large extent, are lists of questions aimed at investigating the sinner and his sins. Nevertheless they prove to be a useful field to define the values of the “passato prossimo” and the “passato remoto”. In the two texts, the two tenses have a clearly distinct distribution. The former has a perfective value, the latter has an aoristic value and, regardless of a temporal criterion, they occur according to this aspectual opposition.

Modelling and development of a generic observatory to harvest and analyze big data
2021
Big Data fascinate, both because of the value they hold that can provide a significant advantage in decision-making, and because of the challenges that their exploitation represents. These challenges are present at several levels of analytics workflows. At the level of the creation of software architectures, the volume and the velocity require at least enough performance to handle the ingestion and storage of data. The data variety has also an impact, as several new storage systems have emerged, each one corresponding to a specific need. The polystores are systems that integrate this diversity, to gain flexibility compared to the data warehouses, now too rigid. However, this diversification…
